To Iall 'whom itmcy concern:

Be 'itknown thatIJRKENNEDx DO UGAN, a citizen oi the `United States, r residing at Minneapolis, in the countyof-Iennepin and State of Minnesota, have invented'fcertain new and useful Improvements 4,in Glasolene- Tnrhes, l0f which the .following iS a .Specificajhad therein Ato the accompanying drawing.

My invention relates to improvements lin Y.gasolene torches, and pertains more particularly to those used by tinners, plumbers and painters.

'Theobject of my inventionis to provide a :gaso'lene torch in which the required kair pres- {Surefcan `atall times be maintained, thus =insuring of a more even feedofgasolene to the burner., and vnecessarily .a constant and uniform .ilame.

Another object of my invention is to provide .a torch of this character, which can be vmore easily filled, and which can ,also be iilled while in operation.

Astilllfurther object of my invention is to provide .a torch in which the pump, tank and pressure reservoir are inalight compact form,

' Laigld having means whereby either airor gaso- `iene may be pumped to the pressure reservoir aste/,quired- In the accompanying drawings, Figure l7 is .a perspeetivev view of vmy improved torch. .Fig.j2, isa vertiealsectional view. Fig. I3, is a Ytop, plan view of Fig. 1, and Fig. l, isa side elevation Apartly in section, ofamodification.

Reierringnow to the. drawings 1 .represents a cylindrical gasolene reservoir, whiehis 4arranged in a vertical position, and is closed by the top :and bottom 2 and 3.- Arranged Within said Igasolene reservoir `is an air vand gasolene pressure reservoir i which extends fthrough the top .and `bottom 2 .and 3 of the gasolene reservoir, land lis closed by the top and l.bottom 5 .and 6. The gasolene reservoir is provided with .a filling koriiice .7 which is closed by a screw-cap 8. Extending inwardly-through the top 210i thegasolene reservoir 1, is a suction .pipe 9 -which l,extends downwardly adjacent the bottom of the reservoir. Connected to the ,upper end of the said suction pipe 9 on the outside of the reservoir, is a conduit 10 which is provided with the enlarged rounded portion 11 which surrounds the upper end 12 of the pump barrel 12. The said conduit above the suction tube 9 is provided with an upwardlyi vthereinin which is a cork disk 15 to :form a tight `joint 'between 4the tube and the cap. The cap is provided with holes 16 which .allow of the inrush oi air to the tube when the cap is screwed upwardly, the object and operation `of which will be hereinafter more vfully described.

The pump barrel 12, as .heretofore stated, extends through the rounded enlar ed ,por-

tion 11 of the conduit 10 and said arrelis provided with openings 17 communicating 'with .the conduit, and through which either the oil or airpassesto the pump barrel. The upper end ofthe pump barrel is provided at Aits upperend with a stuiling box y18 through which passes the pump rod 19 carrying atits lower end the pump sucker 20. Rigidly secured within the lower end oi the pump Vbarrel 12 is .a block 21 having a valve seat 22.

'The lower end of the pump Abarrel has a ,plug 23 `screwed therethrough, and extending upwardly within the same. The said plug; is provided with a vertical recess 24 in which `is arranged a coil spring 25, and extending within said recess and through the coil spring, is .the valve stem 26 which is provided with'a stop 2,7 engaged by the upper end ofthe `coil spring, and 1by means of which the .stemjis normally held in an upward position. The upper end of thestem 26 passes into a recess 28 of the valve 29, the said4 valveis seatedjin the valve seat 22, and normally closes the opening 30 through the plug. l

Secured to one side of the lower end of the pump barrel and in communication therewith, is a pipe 31 which extends below the -gaso'lene reservoir, and in communication with the .air and `gasolene pressure chamber adjacent its lower extended end.

Extending downward ythrough the 4top 5 of the .gasoleneand air pressure reservoir 4, is a pipe ,32 which extends down adjacent the lower end thereof. The upper end of said pipe 32 carriesthe burner 33 which is of any welhknown structure, as this kforms no part of my invention, as theobject of myinvention is to provide a torch wherein an even ,and A`constant supply of oil is fed to the burner.

In Fig. al, l ,have shown a ymodiiication in `which the same principles are involved, but Ainstead of having the -two reservoirs one withinthe other, they are separated. The oil reservoir in the modification is placed upon one side of the pump 12, and the pressure reservoir on the opposite side. The

communication between the pump and oil reservoir is the same as that of the preferred form, but the pump is slightly changed as the automatic valve 35 is not carried thereby, but is carried by the pipe 34 communi=n eating with the pump and the pressure reservoir, as indicated at 35. -Y

In operation, the tank 1 is filled' with oil` through the orifice 7, and the cap is then placed thereon and the torch is practically in readiness for use. Then it is desired to light or place the torch in condition for immediate use, the cap 14 is unscrewed, so that air enters the conduit l() and passes into the pump, and is pumped out through the valve 29, and into the pipe 31 to the pressure reservoir, where the air is compressed. After the proper pressure is obtained therein the cap 14 is screwed tightly down and the cap 7 of the oil chamber is removed or loosened, so as to admit air to the tank. The pump is then worked, which draws the oil from the reservoir through the pipe 1() to the pump, and then forces it out through the pipe 3l to the pressure reservoir or tank at its lower end and compresses the air thereabove until the desired pressure is obtained. The oil by this pressure, is forced out through the pipe 32 to the burner, and by working the pump occasionally, the oil is forced into the tank and proper pressure retained.

By the structure above described, the proper pressure can at all times be retained within the pressure tank, and the burner does not have to be extinguished to 'lill the gasolene reservoir, as its communication with the pressure reservoir is closed through the check valve in the pump, and thus the filling of the tank does not reduce the pressure within the pressure reservior.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is

1. An apparatus ot' the character described, comprising an oil reservoir having a filling oriiice, a ressure reservoir extending through the oi reservoir, a pipe entering the upper end ofthe oil reservoir and extend.- ing adjacent the bottom thereof, a )ump barrel extending transversely through the said pipe and having openings therein communicating with the said pipe, the said vipe having an air port, means for contro ing said port, an automaticallyclosing valve within the lower end of' the ump barrel, a pipe in communication with tlie pump barrel below the valve and having its opposite end in communication with the pressure reservoir, and a burner supply pipe entering the tending to the lower end, and a burner carried by the upper end of the said pipe.

2. An apparatus of the character described, comprising an oil reservoir, a pres- -sure reservoir within the oil reservoir, a pump on the outside of the oil reservoir and 1n permanent communication with the lower Aend by means of a pi e, said pipe having an air inlet, a cap for c osing said air inlet, a pipe communicating with the lower end of the pump and extending below the oil reservoir, and communicating with the )ressurc reservoir, and an automatic check va ve controlling the last named pipe.

3. An apparatus of the character described, comprising an oil reservoir, a pressure reservoir, a pump adjacent the same, a pipe connected to the upper end of the pump and passing through tie upper end of the oil reservoir and extending adj acont the lower end thereof, said pipe intermediate the pump and reservoir having an upwardly extending tube having openings therein, a cap screwed 4upon said tube and having openings adapted to register with the openings in the tubes, a pipe connected to the lower end of the pump and the lower end of the liressure reservoir forming a rigid connection. between the pump and oil reservoir, and a check valve for allowing air or oil to be forced from the pump to the pressure reservoir and prevent ing back pressure.

4. An apparatus of the character described, comprising an oil reservoir, a pressure reservoir extending therethrough, a. pump adjacent the oil reservoir, and parallel therewith, a pipe connected to the u )per ond of the pump and passing through the upper end of the oil reservoir, and extending adjacent the lower end thereof, said pipe intermediate the pump and reservoir having an upwardlyextending tube having openings therein, a cap screwed upon said tube and having openings adapted to register with the openings in the tube, a pipe connected to the lower end of the pump and the lower end of the pressure reservoir below the oil tank, and the two pipes forming rigid connections between the reservoirs and the pump, a check valve for allowing air or oil to be forced from the lower end of the pump to the pressure reservoir, and preventing back pressure, and a burner having a pipe extending within the pressure reservoir.

In testimony whereof l aliix my signature in presence of two witnesses.
